Meghan Trainor is drawing criticism and praise after changing the lyrics to her 2014 hit “All About That Bass” to reference her recent breast surgery. During a headline performance at iHeartRadio’s KIIS-FM Wango Tango event, the 31-year-old singer updated the original line “Yeah, it’s pretty clear, I ain’t no size two” to “Yeah, it’s pretty clear, I got some new boobs,” as seen in a video shared by @1027kiisfm on TikTok.

Some fans viewed the change as contradicting the song’s original message of body positivity. One user commented, “Big is beautiful until you’re rich enough to change it,” while another said, “Her singing this song is peak irony.” Others argued she no longer represents the anthem’s intent.
However, many fans defended Trainor’s decision, noting that body positivity includes making choices that support one’s health. One commenter wrote, “She made the song to stop shame, not to shame change.” Another added that Trainor has grown, started a family, and is focusing on personal well-being.
Trainor, who shares two sons with husband Daryl Sabara, has previously spoken about her physical transformation, crediting the diabetes drug Mounjaro, lifestyle changes, and regular training after giving birth to her second child.
In April, she addressed criticism on Instagram following her appearance at the Billboard Women in Music 2025 ceremony, where she was honoured with the Hitmaker Award. “No, I don’t look like I did 10 years ago,” she wrote. “I’ve been on a journey to be the healthiest, strongest version of myself... and I’m so glad I did because I feel great.”
